Unit Six: Array

computers that are connected to share resources using a data link

network of smaller networks connected using a specific set of rules

internet protocol, the rules of the internet (internet layer)

user datagram protocol, breaks data into datagrams (transport layer)

advanced research projects agency

defense advanced research projects agency

a packet-switching network, first network to use TCP/IP protocols

department of defense model

application, transport, internet, link

defines rules for different user application

internet message access protocol, used for email (application layer)

post office protocol, used for email (application layer)

simple mail transfer protocol (application layer)

voice over internet protocol, used for telephony (application layer)

file transfer protocol, transfers files between client and server (application layer)

secure shell (application layer)

remote desktop protocol (application layer)

hypertext transfer protocol (secure), provides encrypted connection between browser and website (application layer)

hypertext markup language, standard language for creating web pages (application layer)

cascading style sheets (application layer)

files stored on a computer (application layer)

client sends request to server and server sends requested information back (application layer)

a name given or linked to an ip address (application layer)

top level domain, ex: .com (application layer)

internet assigned numbers authority, manages domain names (application layer)

internet corporation for assigned names and numbers (application layer)

uniform resource locator, locates specific files from domain (application layer)

any domain part of another domain (application layer)

domain name system, determines IP address (application layer)

internet service provider, ex: verizon (application layer)

13 total, contains every single domain name and IP address in the world (application layer)

transmission control protocol, breaks down request into packets (transport layer)

lets client know if all packets sent made it to the server

even if there is an error, the system can work properly

the IP creates addresses and attaches them to each packet (3rd layer)

uses 32-bit addresses, allows for 2^(32) addresses (ex. 43.234.2.752) (internet layer)

internet engineering task force

media access control address, unique physical address (internet layer)

manage interface between physically connected nodes on local network (4th layer)

address resolution protocol (link layer)

reverse address resolution protocol (link layer)

neighbor discovery protocol (link layer)

physically transfers binary data from client to server

device that handles both modulation (for outgoing signals) and demodulation (for incoming signals); (physical internet layer)

directs internet traffic (physical internet layer)

one way to send packets, not the fastest or most efficient, can be disturbed by things like lighting

fastest way to send packets through infrared light in the form of hair thin, transparent fibers called fiber optic cables

type of fiber optic cable, thicker and can send light at different wavelengths through the same fiber, cause distortions over longer distances

type of fiber optic cable, used for longer distance, thinner and carry just one wavelength or mode

travel farther since they face less electromagnetic interference and can better pass through objects

the number of bits that can be processed per second

the amount of resources available to transmit data

round-trip time information takes to get from client to server and back
